FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
348 AM AST WED JAN 16 2019
DISCUSSION
KDBI VALUES AND TEN-HOUR FUEL MOISTURE ACROSS THE
SOUTHERN COASTAL PLAINS OF PUERTO RICO CONTINUE TO REMAIN ABOVE
600 AND 10% RESPECTIVELY, SUGGESTING THAT THE VEGETATION REMAINS
VERY DRY. THE MAIN LIMITING FACTORS, HOWEVER, FOR FIRE SPREADING
WILL BE THE LIGHT WINDS OF LESS THAN 15 MPH AND AN INCREASE IN
CLOUDINESS, WHICH WILL PREVENT RELATIVE HUMIDITY VALUES FROM
DROPPING TO THE CRITICAL THRESHOLD LEVELS FOR A PROLONGED PERIOD
OF TIME. THEREFORE, THE FIRE DANGER IS DEEMED TO BE LOW TO
MODERATE FOR TODAY.
